i once heard a country song that says God does not make mistakes, u are loved by God for who u are and who he is. it is our unworthiness that makes us worthy, grace is not for the worthy or else it wouldn't be grace. u need find what makes u happy, music, movies, books and such as and focus on what attracted u to the faith in God in the first place and meditate on that, he is not a God of sufferings but of great joy. look in a mirror and say to yourself, i am beautiful and holy in the sight of God and excepted by him made, and have some ice cream, it always makes things better
